T at whom it incty concern: 1

Be it known that 1, JOHN NASH, a citizen of the United States, residingat North Yakima in the county of Yakima and State of Washington, haveinvented a new and useful Vehicle-WheeL of which-the following ispecification.

This invention relate -vehicle wheels,

and is designed to provide r cushioning the same at the hubthereof'rather than at the a rim of the wheel, and to accomplish theseresults in a new and novel mamierwithout in any degree reducing thestrength and durae f bility of the wheel.

It is furthermoredesi ned to enable the convenient assemblage 0 thewheel, and to permit replacing of any broken'parts thereof. With theseand other objects in view,- the present invention consists in thecombination and arrangement of parts as will be hereinafter more fullydescribed, shown in the acpresent invention.

' n u o I vframe structure within which 1s centrally hung a hub which iselastically yield'able.

companying drawing and particularly pointed out in the appended claims,it being understood that changes in the form, proportion, size and minordetails may be made, within the scope of the claims without departingfrom the spirit or sacrificing any of'the advantages or the invention.

v in the drawing: Figure 1 is aside elevation of a wheel embodying thefeatures of the with one of the side members of the wheel removed. Fig.3 is a cross sectional view of Fig. 1:. Fig. 4 is an edge view of thewheel having its rim broken away and disclosing a modified form of sring.

Like characters 0 vreferencedesignate corresponding parts in all of thefigures of the drawing.

, The present wheel includes a rigid skeleton The frame includesduplicate half sections,

each section including a central body memher 1 having a concentricopening 2, thereby producing a ring-shaped body. From this body radiatespokes 3, which are preferably integral and are connected at theirouterends by a circular rim 4 which is provided at-its outer edge withan annular flange 5.

' It will here be explained that the parts of Fig. 2 is a similarvieweach rim member are integral and therefore may be of cast metal. Theframe members are assembled face to face, as in Figs. 3 and 4, and areconnected by means of bolts or other fastenings 6 which are passedthrough the enlarged outer terminals 7 of corresponding spokes, with theinner edges of the rims 4 abutted,'whereby an annular channel is formedentirely around the rim of the wheel for the reception of a solidyieldable tire 8, preferably a rubber ring. The frame'members arefurthermore connected by an annular series of fastenings 9 iercing theopposite body members 1 in a res ective spokes. p

he' hub 10 of the wheel is an open ended body members 1, and providedwith external annular end flanges 11 and an intermediate annular flange.12. The fastenings 9 of course extend longitudinally through thecylinder and are normally disposed concentric with respect to an annularseries of open ended sleeves 13 carried by the inner peripheryof thecylinder and preferably integral therewith.

Extending between the hub and the rim of each side of the intermediateannular flange 12 ofthe hub. Each spring 14 consists of a flat springbar which is bowed into substantially semi-circular shape, with itsinner end terminating in an eye 15 embracing a bolt, rivet, orsuitablefastening 16 which also 19 embracing the adjacent fastening 6. whichconnects the rims of the wheel sections; The eyes, of course, looselyembrace the fastenings so as to rock thereon when the springs are undertension. The springs of one set are disposed between the intermediateflange 12 and one of the fiangesll, while the other set aredisposedbetween the intermediate flange 12 and the other flange 11, -whereb thetwosets of springs lie in substantia y parallel planes. Occupymg themiddle of the hub there is a cushion 18, preferably of rubber which hasa v a metallic sleeve or boxing 19 for the recepinement with the passesthrough the flanges 11- and 12. v The. outer end of the springterminates in an eye cylinder of substantially the diameter of the thewheel are two sets of springs, one set at concentric opening in which issnugly fitted loaded sufficiently to force the hub 'down' tionof'theadjacent endof the axle 20. The

outer periphery of the cushion 18 has a generally circular form, and isprovided at regular intervals with concaved' seats 21 snuglyreceivingthe respective "sleeves 13, whereby the cushion is held againstcreeping.

From the" foregoing description, it will be understood that theduplicate half sections of the wheel constitute a rigid frame in whichthe hub is yieldably supported by the springs 14, whereby the 'hub'iscapable of yielding independently of the rigid frame of the wheel,thereby to effectually cushion any jars to which. the wheel issubjected. It will herebe explained that the rubber tire. 8 is notemployed to cushion .the wheel so much as it is employed to-re'duce thenoise thereofwhen the wheel is running.

Should the .wheelbecome there would be too much straln upon-the springs,and to relieve the springs of such strain is the function of the'rubbercushion 18 which comes into play when the vehicle is be centered withinthe wheel inthe normal condition of the latter, as the tendencyof thesprings of one set is offsetby the tendency of the springs of the otherset to move-the hub laterally within the wheel.

Upon reference to Fig. 4 of the drawing, it

will be noted that I contemplate employing a slightly different shape ofspring, desig-' nated 14, which tapers outwardly from its inner. end,whereby its inner end is stiffer than its outer end which tends toprevent dishing of the wheel, otherwise the construction of the wheel isthe same as hereinbefore described. v

Having thus described the invention, What is claimed is:

1. A wheel comprising a rigid frame made up of complementary halfsections, each section including a central body having an axle opening,spokes radiating from the body, and

a IlIIl connecting the outer ends of the spokes,

fastenings connecting corresponding spokes of the two sections, a hubindependent of the wheel sections, springs extending between the hub andthe fastenmgs and means within the hub for limiting its movement.

A wheel comprising a rigid frame, a huh I overloaded,

independent of the frame, springs extending between the hub and theframe to yieldabli support the hub, a cushion carried by the hub, and anannular series of stops carried by the frame and disposed in position tobe cushioned when the hub is ,displaced beyond a predetermined limit.

i 3-. A wheel comprising a rigid frame, an open ended hub independent ofthe frame,

springs connecting the hub and the frame, an annular series of pinscarried by the frame and extending through the open ends of the hub, acushion carried by the hub wi-thin'the area bounded by the pins, thepins constituting stops adapted to be cushioned when the hub has beendisplaced beyond a-predeterr mined limit.

4. A vehicle wheel comprising a frame, an open endedhub within theframe,

springs connecting the hub and theframe,

open ended sleeves rigidly carried-within the hub, a cushion snuglyembraced. by the sleeves, and pins carried by theframe and extendingthrough the iopenends of the sleeves, said pi-ns constituting stops for,en-

gagement by the sleeveswhen the hub has been displaced'toa predeterminedlimit.
